Macerators

Macerators are an important industrial tool used for the processing and treatment of industrial solid wastes comprising of wood, textile, plastics, paper, rubber, bones and skin. With a capacity to reduce solid wastes into finer particles of grain size of up to 3.5 mm and fibrous size of up to 1.5 cm2 approximately. Macerators feature a wide range of functions starting from preparation, line chopping mixing, processing and treatment of waste products in wide range of industrial applications. Efficiently engineered to avoid clogging of pipes, fittings and pumps, macerators also help in saving the cost of pipe fittings by opting smaller diameter against the predetermined flow.

PMT Series

PMT series are designed for installation on the side of a tank or basin.  This unit can be mounted vertically or horizontally. In this, the motor is directly attached to macerator chamber to form a single unit.  Inside the Macerator, the impeller with replaceable cutting edges , rotates inside the stationary cutting ring, which macerate the  particles to smaller size. Macerators of this design have a delivery head of 3 m and can thus return the chopped solids to the main flow under their own power.

Flange positions
Suction Flange :  Axial or vertical downwards
Delivery Flange : Normally radial upwards. Adjustable by 45o each as per hole  arrangement

Flange Design
Connection dimensions as per DIN Standard

PMI Series

PMI Series are designed for installation in the piping. This unit must be installed vertically. In this, the motor is directly attached to macerator  chamber to form a single unit.  Inside the Macerator, the impeller  with replaceable cutting edges ,
rotates inside the stationary cutting ring,  which macerate the particles to smaller size.
For this model either the helical pump or progressive cavity pump must be installed to suck the solids through the macerator and pump them into the plant for further treatment.

Flange positions
Suction & Delivery Flange :  Opposite, inline and same Dimension

PMT-R Series

PMT series are designed for installation on the side of tank or basin.This unit can be mounted vertically or horizontally.Inside the macerator, the impeller with replaceable cutting edges, rotates inside the stationary cutting ring, Which macerate the particles to smaller size.Macerator of this design have a delivery head of 3m and can thus return the chopped solids to the main flow under their own power.This series is available in without motor configuration.

The Inside Picture
Technology

Macerators are an important industrial tool used for the processing and treatment of  industrial solid wastes comprising of wood, textile, plastics, paper, rubber, bones and skin.

Mechanical Seal

Mechanical seal with highly wear resistant hard metal seal rings and rubber bellows secondary gasket . The entire seal assembly is either oil lubricated or water lubricated with external circulation unit.

Materials:
Rotary seal ring                    silicon carbide
Stationary seal ring              silicon carbide
Bellows                                  acrylonitrile-butadiene rubbers (NBR)
O-ring                                     acrylonitrile-butadiene rubbers (NBR)
Metal parts                            stainless steel

Bearing / Lubrication

On the drive side by a reinforced cylinder roller bearing as per  DIN 5412 which is greased for its service life. On the end side by a grooved ball bearing as per DIN 625.

Motor

Motors developed and manufactured are standard. Motors are surface cooled TEFC motor, suitable for continuous and intermittent application. Available in both F and H class insulation.

Anti-Swirl Fins

Inlet chamber contains 2 large anti-swirl fins to stop 'spinning' of textiles and to direct solids in suspension into optimum flow path for maceration through impeller.

Cutter Ring

Investment casted alloy steel (1.2601) with optimum combination of both hardness and resilience - positively clamped in position by inlet chamber, hardened and internally ground for maximum cutting efficiency.

Tri Hammer Impeller

High corrosion resistant investment casted impeller with replaceable cutting inserts (Complete impeller 1.4312 with stellite segments).  There are three hammers with more blows per revolution better balanced rotation. Impellers having pusher blades to avoid clogging in the down stream side.

Installation

Control Panel

Features:
1. Control of the seal water supply unit for the shaft sealing  
2. Automatic change of the sense of rotation with every start in order to increase the service life of the cutting tools or after
3. Reaction of the overload protection to prevent clogging
4. Control of the safety device of a stand by pump to be put in operation if necessary

Functional characteristic:
The Macerator control is activated through a Start / Stop switch. The solenoid valve of the seal water unit opens after the release signal (e.g. external pressure or level switch or push button control) and mechanical seal is flushed with sealing liquid. Both Macerator and pump switches on automatically after 30 sec. Once it is switched off, it stops working immediately while seal water unit shuts off with a 30 sec delay. Every sense of rotation of the Macerator is altered automatically with every new start. To prevent clogging, the Macerator control monitors the motor current. When the current limit is exceeded, the contactors are activated automatically and sense of rotation is changed. If the current remains above the limit, the sense of rotation changes again. This procedure will be repeated up to 4 times. If the current is still above the limit, both Macerator and pump switches off automatically.
